Bounty managers please kindly start hiding emails in your spreadsheet because I always like using new email for bounty participation and I surprised that there are many offer mails in my email account, some are free airdrop some are affiliate marketing offers, I still remember that some people are selling email addresses online, it will be easier for such people to go through bounty spreadsheet and pack the whole email address
Maybe that is intentional as they wanted to sell your Emails to 3rd party group so Exposing in Spreadsheet will make it clean from their hands if tons of emails sent to our account because they can easily denied and reasoning is you are exposed in the Sheet.
instead of joining bounties with that kind of manager better find others that will protect your privacy and won't take advantage of situation.
